Sparse pitch-class spectrum for a C major triad.

A fundamental question in cognitive science concerns the representational structures that underlie human intelligence. Computational approaches to harmony cognition require a well-defined set of harmony representations that characterise musical sound, the low-level sensations elicited by this sound, and the cognitive representations that humans derive from these sensations. The hrep package implements a network of such representations within an object-oriented framework, thereby provididing a natural basis for the computational modelling of harmony cognition. This work is described in Chapter 2 of my PhD thesis, and the corresponding software is available and documented online.
